Updated at 5:30 p.m. Wednesday: Revised to include a severe thunderstorm watch for North Texas.

A tornado touched down in Denton on Tuesday as thunderstorms swept through Dallas-Fort Worth at the start of a rainy week.

Rain is possible every day through Saturday in North Texas, with chances increasing in the middle of the week. The storms could cause flooding and produce damaging winds and hail, according to the National Weather Service.

By the time the week is over, 2 to 4 inches of rain could fall, according to KXAS-TV (NBC5) meteorologist Grant Johnston.

Tuesday

About 5:45 p.m., the weather service received reports of a rotating wall cloud in the Lakeside area, northwest of Fort Worth. Those storms moved northeast toward Denton, prompting the weather service to issue a tornado warning for Denton, Aubrey, Pilot Point and surrounding areas.

A brief EF-1 tornado was confirmed northeast of the Texas Woman's University campus at 6:56 p.m.

The tornado, which had maximum wind speeds of 90 mph, then traveled northeast near Denton ISD's natatorium near Loop 288, according to the weather service. Most of the damage affected trees, not homes, according to the weather service.

The tornado is the first in Denton since March 2017, according to weather service records.

After a storm survey Wednesday morning, the weather service also confirmed an EF-1 tornado touched down Tuesday evening in east of Justin, with maximum wind speeds of 90 mph.

Despite reports of a rotating wall cloud near Eagle Mountain Lake on Tuesday, a survey team did not find evidence of a tornado in the area, only sporadic wind damage.

A flash flood watch continues for much of North Texas through 7 p.m. Thursday. The watch includes Dallas, Denton, Collin and Tarrant counties.

Wednesday

“Wednesday’s looking like widespread showers and thunderstorms, including the risk of severe storms,” Johnston said.

The National Weather Service issued a severe thunderstorm watch for much of North Texas, in effect until 1 a.m. Thursday. The watch includes Dallas, Denton, Collin and Tarrant counties.

The area could see up to 2 inches of rainfall along with the possibility of multiple rounds of heavy showers. Flooding could be a concern, especially south of Interstate 30, according to the weather service.

The greatest chance for showers and storms in Dallas-Fort Worth would be Wednesday afternoon into the evening hours, according to the weather service. Some storms could produce damaging winds and even hail.

NBC5 meteorologist Rick Mitchell said the prediction center's outlook does not mean everyone will see severe weather, only that conditions for severe weather would be favorable if storms could develop.

Thursday through Saturday

A cold front expected to move through North Texas on Thursday could bring some added moisture to the area, which may allow rain chances to linger through Saturday, weather service meteorologist Juan Hernandez said.

The area saw more than double the amount of normal rainfall for the month of April, with 6.75 inches of rain recorded at DFW International Airport. May is usually the rainiest month of the year, with an average of 4.9 inches.
